Abstract

A process for controlling the glycosylation of protein in a cell wherein the cell is genetically engineered to produce one or more enzymes which provide internal control of the cell's glycosylation mechanism. A Chinese hamster ovary (CHO) cell line is genetically engineered to produce a sialyltransferase. This supplemental sialyltransferase modifies the CHO glycosylation machinery to produce glycoproteins having carbohydrate structures which more closely resemble naturally occurring human glycoproteins.
